Research on the Adjustable LAVAL Nozzle during Pneumatic Conveying

Abstract:

The relationship between the input and output (displacement of adjusting lever and air flow) of adjustable LAVAL nozzle is deduced. In the pneumatic conveying condition, finite element analysis to adjustable LAVAL nozzle is simulated, and its steady-flow effect is proved. Experiments show the adjustable LAVAL nozzle is energy-saving, can improve the quality of conveyed material, and reduce percentage of damage.
